This is due to using copy-if-change to avoid unnecessary copying for (at least) the main executable and the shared libraries under Unix.

Now, copy-if-change of course uses "cp" for doing its work, whereas in the GNU build environment we would typically use $INSTALL and its variants for doing so (and the latter would always set the mode to 755 or 644 [for data]).

The simplest fix to me seems to enhance copy-if-change to

I guess there is a similar issue with things "installed" by move-if-change.
